  1. The isolates C4B8, C5B9, C4B3 and C4B8 originated from a pig herd in Hong Kong Special Administrative Region. Minimum inhibitory concentrations (MIC) were determined by agar dilution and interpreted according to [11] for tylosin, lincomycin and to [10] for tiamulin.
  2. NK not known, S susceptible, I intermediate, R resistant
